Yes, it is confusing, we know. The manufacturer prices wallpaper as "single rolls", BUT they only package/ship them as "double" rolls. What does that mean? Bare with us, but think of it like rolls of paper towels! They take 2 single size rolls and make one big roll. That's basically the same thing with wallpaper.
Example: When you order wallpaper, you must order in even numbers (2,4,6,8,etc. of single rolls). For every 2 rolls you order, you'll receive 1 double roll.
If you are still having trouble with how many rolls you need to order, feel free to live chat us or email email@example.com and we will be happy to assist you!
